HARRY R. SINCLAIR, 0F WORCESTER, MASSACHUSETTS, ASSIGNOR TO HENRY S. WARNER, OF BROOKLINE, MASSACHUSETTS.

EGG-BEATER.

I '0 all whom it may concern Be it known that I, HARRY R. SINCLAIR, a citizen of the United States, residing at orcester, county of Worcester, State of Massachusetts, have invented an Improvement in Egg-Beaters, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to devices of that class used for beating eggs, whipping cream, etc., and particularly to those devices which are provided with a dasher secured to a spirally-twisted stem which is capable of reciprocation in a frame, whereby when the stem is reciprocated, the dasher will be given a whirling up-and-down movement.

My present invention relates to an improved construction of frame and has for its object to provide a device of this nature which is simple and can be inexpensively manufactured.

The features wherein my invention resides will first be described and then pointed out in the appended claims.

Referring to the drawings wherein I have illustrated a selected embodiment of my invention, Figure 1 is a side elevation of a beater or mixing device made in accordance with the invention. Fig. 2 is a section on the line z-e, Fig. 1. Fig. 3 is a side view of the handle portion taken at right angles to Fig. 1. Fig. 4 is a sectional view showing a step in the process of manufacture.

The complete device comprises a frame adapted to be set into a glass jar or other receptacle, a dasher and a spirally-twisted stem carrying the dasher and capable of having a reciprocating movement in the frame. The dasher is shown at 1 and may have any suitable or usual construction. As herein illustrated, it is made of a disk of sheet metal which will preferably be provided with apertures 2 and if desired may be formed with a plurality of up-turned ears 3, although this is not essential. This dasher is secured to the lower end of a stem 4 which has a knob or hand-piece 5 swiveled to the upper end thereof. The stem 4 is made of a ribbon-like metal strip which is spirally twisted as shown.

The frame comprises a handle portion 6 and a body portion 7 The body portion 7 is shown as formed of wire which is bent to Specification of Letters Patent.

present two sides 8 between which the dasher 1 operates and a bottom or foot portion 9 which is adapted to rest on the bottom of the jar, glass or other receptacle. This foot portion 9 may be made of any suitable shape and as illustrated in the drawings it is approximately semi-circular in shape and stands at one side of the uprights 8. The handle portion 6 will preferably be made of a strip of sheet metal bent into the fl-shape shown in the drawings, the portion 19 thereof having an aperture to receive the stem 4. The lower ends 10 of the arms of the handle portion are provided with apertures 11 and 12 which receive the ends of' the wire from which the body 7 is made. The apertures in each arm of the handle portion 6 are situated out of line with each other vertically and the apertures in one arm are in alinement with those of the other arm. One end 13 of the wire body portion extends through one pair of alined apertures in the two arms 10 of the handle portion 6 and the other end 14 of said wire body extends through the other apertures.

The lower ends of the arms 10 are shown bent inwardly slightly and are placed a distance apart slightly greater than the greatest diameter of the stem 4. The apertures 11 and 12 in each arm 10 are so spaced from each other that when the ends 13 and 14 of the wire are in the apertures, said ends are a distance apart just sufficiently greater than the thickness of the stem 4 in the narrowest direction to permit said stem to freely play between the ends. With this construction a rectangular opening will be formed between the ends 13 and 14 and arms of the n-shaped member which will approximately fit the cross-sectional shape of the stem. As a result, when the stem is moved up and down, the engagement of said stem with the ends 13 and 14 of the wire body will cause said stem to turn because of the spiral construction of the stem and this turning movement will, of course, be communicated to the dasher 1. As a result, the dasher will have a combined rotary and upand-down movement.

In order to make a rigid and permanent connection between the wire ends 18 and 14 and the arms 10 of the handle portion 6, I propose to make each wire end with a recess 16 in one side which is occupied by the metal of the arms 10 when the parts are assembled. In the manufacture of the device, I propose to make the apertures 11 in which the extremities of the ends 13 and 14: are received of the same diameter as the wire. After the wire ends have been inserted through the apertures the metal of the arms 10 is upset to cause it to flow into and fill the recesses 16. This can be done by subjecting the arms edgewise to suitable dies after the wires have been inserted in the apertures 10 and 11.

The handle portion 6 will preferably be made with the widened upper portion 18 to prevent the fingers and thumb of the operator from slipping off therefrom. This handle portion 6 made of sheet metal makes a very convenient handle by which the device may be held.

While I have illustrated one embodiment of my invention, 1 do not wish to be limited to the constructional features shown.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a beater or mixer, the combination with a frame comprising a I'l-shaped handle portion, the lower end of each arm of which has two apertures out of alinement in the direction of the length of said handle portion and a body portion formed from a piece of wire, each end of which is inserted through an aperture in each arm, of a beating element comprising a dasher and a spirallytwisted stem, the latter extending through an aperture in the handle portion and between the ends of the wire body, said ends coacting with the spirally twisted stem to cause the latter to rotate as it is reciproeated vertically.

2. In a device of the class described, the combination with a frame comprising a h andle portion presenting two sides each having two apertures situated out of alinement in the direction of the length of the handle and a body portion formed from a wire having its ends inserted through said. apertures, of a beating element comprising a spirally-twisted stem located between the sides of the handle and between the ends of the wire body and a dasher connected to said stem, said handle portion having means for guiding the stem and the ends of the wires cooperating with the spirally twisted stem to'canse the latter to turn as it is reciprocated.

3. In a device of the class described, the combination with a frame comprising a handle presenting two sides and a body formed from a strip of metal bent into shape and having its ends secured to the sides of the handle portion at points out of alinement with each other in the direction of the length of said handle portion, of a heating element comprising a spirally-twisted stem located between the sides of the handle portion and extending between said ends of the body, the latter co-acting with said spirally-twisted stem to cause it and the dasher to rotate as it is reeiprocated longitudinally.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
